Example 10 FOR X=1T09
20 FOR Y=1TO9
30 PRINT X#*Y; Inner loop
40 NEXT Y
50 PRINT
60 NEXT X
70 END
Outer loop
10 FOR A=1 TO 3——,
20 FOR B=1 TO 5——+
30 FOR C=1 TO 7
110 NEXT C
120 NEXT B————_~ 110 NEXT C,B,A
130 NEXT A
When loops C, B, and A all end at the same point as in the example above, one
NEXT statement may be used to indicate the end of all the loops.
Incorrect example:
FOR J=1 TO 10
Fron J=KTOK+5
NEXT J
Different control variables must be used in each loop.
FOR 1=1 TO 10
FOR J=K TO K+5
NEXT |
NEXT J
Loops may not overlap each other.
Note:
The syntax of BASIC does not limit the number of levels to which loops may be
nested; however, space in the memory is required to store return addresses for each
level, so the number of levels is limited by the amount of free memory space available.
The CLR and LIMIT statements cannot be used within a FOR ~ NEXT loop.
